Re: “Bridging the gaps: getting evidence into practice.” 1 Knowledge and science are considered identical by the public. But from a technical terminology standpoint, knowledge refers to “awareness of a fact;” while science refers to “systematically organized body of knowledge.” Knowledge management should balance knowledge and science. Patients must be educated with scientific facts in layman’s language, and reliable and responsible facts need to be transmitted in the most responsible, educative ways. Prevention rests on such information. CMAJ, by publishing this article, has opened a way for proper dissemination of knowledge in the field of medicine.
